Your Question:
\n" ); document.write( "2x+y=12
\n" ); document.write( "x-y=3
\n" ); document.write( "----------------------------------------------------------------------------
\n" ); document.write( "solve for x:
\n" ); document.write( "x-y=3 becomes x=y+3
\n" ); document.write( "----------------------------------------------------------------------------
\n" ); document.write( "substitute for x:
\n" ); document.write( "2(y+3)+y=12
\n" ); document.write( "----------------------------------------------------------------------------
\n" ); document.write( "Solve:
\n" ); document.write( "2y+6+y=12
\n" ); document.write( "3y+6=12
\n" ); document.write( "3y=6
\n" ); document.write( "y=2
\n" ); document.write( "----------------------------------------------------------------------------
\n" ); document.write( "substitute for y:
\n" ); document.write( "x-(2)=3
\n" ); document.write( "x=5
